Description

Method for checking vehicle door passing

Technical Field

The invention relates to a method for checking the passing of a vehicle door, which is suitable for a structural engineer to use, wherein the passing amount is determined by the relative relationship of a vehicle door hinge, a vehicle door lock and a vehicle door outer plate, then the whole vehicle door is rotated to a passing position, and the position simulates the passing working condition of the vehicle door, so that whether the clearance between the vehicle door and peripheral parts (side walls, decorative parts and the like) meets the requirement is checked.

Background

The speed of the car door is generally less than 2 m/s when the car door is normally closed, the speed can be more than 4 m/s under violent door closing and other working conditions (wind power and slope), and the car door can further move along the closing direction at the moment so as to collide with peripheral parts, thus causing the faults of paint collision or part damage and the like; the excessive closing working condition of the vehicle door generally needs the real vehicle to carry out large load (heavy door closing) evaluation, and the collision problem in the real vehicle stage is generally difficult to solve.

The vehicle door is also subjected to simulation analysis through CAE, but the CAE analysis is limited by the CAE modeling precision and the like of parts such as sealing strips, door locks, buffer blocks and the like at present, the analysis result is not accurate, and the method is not suitable for structural engineers to quickly find problems.

Patent document 1(CN108058581B) discloses a method for checking vehicle door parting and a method for designing a vehicle door, which relate to the field of vehicle design, and the method for checking vehicle door parting comprises the steps of determining a vehicle door hinge axis and a vehicle door maximum opening angle; determining a limit region of a front section of a door parting line based on the door hinge axis and the door maximum opening angle; determining a front section of a door parting line according to aesthetic requirements and the limit area; determining the lower section and the rear section of the parting line, and trimming the lower section, the rear section and the front section determined in the previous step to form the complete vehicle door parting line. The method for checking the vehicle door parting relieves the technical problem that the vehicle door body which is subjected to modeling design often interferes in movement in the prior art.

Patent document 2(CN104462699B) discloses a motion checking method based on CATIA cross-section, including: assembling a part to be checked, a side wall assembly and an interference checking part into a product component; building a carrier component in the product assembly, and building a first auxiliary surface and a second auxiliary surface on the carrier component; projecting the product assembly on the first auxiliary surface to obtain an assembly projection surface; in the projection plane of the component, sectioning the parting along the direction vertical to the axis of the hinge, and projecting the structure at the sectioning position on a second auxiliary plane to obtain a parting sectional view; in a parting section diagram, moving the projection of the interference checking component by a preset tolerance distance along the direction of the minimum parting distance and the direction vertical to the parting; rotating the part to be checked to the maximum opening angle by taking the center of the hinge as an original point to form a boundary trajectory line; and measuring the minimum distance between the boundary trajectory line and the projection of the interference checking component, and judging whether the minimum distance is within a preset range. The method has higher precision for checking the movement of the four doors and the two covers.

Patent document 3(CN104462699B) discloses a door hinge, and particularly relates to a door hinge arrangement method. The method for arranging the hinges of the inward turning type vehicle door comprises the steps of determining the positions of the hinges, determining the inclination angles of the axes of the hinges and checking the limit movement of the hinges. The outward turning type vehicle door hinge arrangement method comprises the steps of hinge position determination, hinge axis inclination angle determination and hinge limit movement check. The invention has the advantages of accurately positioning the hinge, realizing the quick positioning of the vehicle door hinges with different sizes, determining the inclination angle of the hinge axis and checking the limit movement of the hinge, ensuring the accurate installation of the vehicle door hinge and the like.
